| As others have mentioned, a pie is consumable, and thus a good one has value even if it isn't original. But a slight change to the original scenario makes asking about originality much more reasonable: Imagine you write a peach pie recipe over the weekend, and you give a copy of the recipe to your friend. They respond: "Wait, how is this different from every other peach pie recipe that's ever been written? It seems really similar to another recipe I have." That's not an unreasonable answer. When I was in a band, one of the most valuable things my songwriting friends and I did for each other was tell each other when our work sounded like something that was already out there. If you make a new piece of software and offer it to a friend to use, it's not unreasonable for them to ask how it's different from something that's out there already. |
Being told any of these things by a friend you show the chair to is entirely pointless and maybe even mean. The only angle that has some level of social acceptability is an angle like "check out this chair that's like what you wanted to build, maybe you could learn something from it", but even that is a 50/50 on whether its taken positively or taken as "oh, you don't think I don't know how to build a chair, wtf bro".
Pie recipes are different. Music is different (VERY different) (incomparable).
